Product Characteristics
The HTC-1600 Coil Processing Line is an integrated coil handling and feeding solution designed for aluminum coil stamping applications, including lithium battery covers, aluminum battery housings, and other precision metal components.
The system combines automatic decoiling, precision leveling, and NC servo feeding to prepare coil material for downstream stamping operations. By coordinating these functions, the production line helps maintain stable material handling, improve strip flatness, and support consistent feeding during continuous stamping.
Aluminum coil processing requires particular attention to material surface protection. Scratches, roller marks, residual curvature, and unstable feeding can affect the appearance and dimensional consistency of stamped components. The HTC-1600 addresses these production challenges through a precision leveling system, an accessible leveling head for cleaning, a servo feeding mechanism, and a material buffering bridge.
Designed for integration with stamping presses, the HTC-1600 provides a coordinated solution for manufacturers processing aluminum battery covers, square battery cases, terminals, and other coil-fed components.
Key equipment features include:
Automatic uncoiling with a coil loading trolley.
Hydraulic expansion mechanism for coil holding.
Six-upper, five-lower precision leveling roller arrangement.
Hinged-open leveling head for easier roller cleaning.
NC servo feeding system for controlled material feeding.
Hydraulic loop bridge with photoelectric sensing for material buffering.
Material support rollers designed to help reduce surface scratching.
The final machine configuration and processing range should be confirmed according to the selected model and the customer's material specifications.
The feeding platform trolley is designed to ensure safe and efficient loading and unloading of heavy coils, significantly reducing manual handling risks. The heavy-duty uncoiler works in coordination with the leveling unit to smoothly guide the coil head into the straightening section and maintain controlled automatic unwinding.
A powered pressing arm prevents coil scattering during rotation, while assisting material entry into the leveler. The uncoiler features a hydraulic sliding block expansion structure, which offers higher load-bearing capacity than traditional pin-type designs and supports coil weights of up to 10 tons, ensuring stable, continuous, and vibration-free unwinding for demanding production environments.
The material leveling machine corrects and levels the material through upper and lower leveling rollers, in conjunction with an uncoiler and high-speed NC feeder. The leveling rollers are arranged with six on top and five on the bottom, made of bearing steel SUJ2, with the roller surfaces processed by wire electroplating and grinding.The machine head is designed to be easily hinged open, allowing for convenient daily cleaning of any impurities or metal oxide layers that may accumulate on the leveling rollers' surfaces, thus preventing material defects such as scratches or marks, especially on aluminum materials.
The servo coil feeder can achieve high-speed and efficient feeding. This machine uses a numerical control operating system, and its user-friendly design and operating concept allow users to quickly become proficient in operating it. The feeding rollers have a hollow structure, resulting in low rotational inertia, high feeding accuracy, and a long service life. The rollers are made of bearing steel and are subjected to high-frequency treatment, tempering, grinding, and hard chrome plating. After feeding with this machine, the materials are smooth and even without any indentations, ensuring that the surface of the materials is not damaged. The main machine has a strong steel structure, high output power, and stable feeding.
During the feeding process, there is no need for manual lifting of materials, and the steel coils can be smoothly delivered to the feeding machine. The steel coils can be buffered by the material arc to ensure that the material belt length can be conveyed into the feeding machine. Hydraulic power is used for lifting and lowering, with a buffering bridge spanning the ends of the leveling machine and the feeding machine. It is raised during feeding and lowered during connected operation. Two sets of photoelectric switches are installed at the material arc, controlling the speed conversion of the leveling machine to ensure that the hanging plates have sufficient length for storage. The material support rollers are covered with rubber on the bearing surface to prevent the material from scratching the surface during passage.
The HTC-1600 Heavy-Duty Uncoiler, Leveler, and Servo Feeder Line is widely used in the lithium battery manufacturing industry, particularly for the automated stamping production of precision aluminum components such as square battery cases, battery covers, and aluminum terminal components.
Designed for high-precision aluminum coil processing, the system integrates uncoiling, leveling, and servo feeding into one compact automated production line, ensuring stable material feeding, excellent flatness, and accurate positioning before stamping. This helps improve overall stamping consistency, dimensional accuracy, and production efficiency.
Typical stamping applications include:
Square aluminum battery cases with high structural strength and reliable sealing performance;
Battery covers requiring multiple punching, forming, and bending operations;
Precision aluminum terminal components processed with accurate blanking and punching for improved electrical conductivity and assembly performance.
The HTC-1600 production line is especially suitable for high-speed automated stamping applications that require stable feeding performance, high surface quality, and consistent precision for lithium battery aluminum components.
Aluminum coil processing requires appropriate handling and contact surfaces to help reduce scratches, dents, and other visible defects.
The HTC-1600 combines coil handling, precision leveling, servo feeding, and material buffering in one coordinated production system. Roller cleanliness, guide alignment, and suitable machine settings remain essential to maintaining surface quality.
The leveling system uses six upper and five lower rollers to apply controlled bending to the material.
The roller arrangement, adjustment range, and material properties influence the achievable leveling result. The required flatness should be evaluated against the actual aluminum material and stamping application.
The hinged-open leveling head provides access to the roller area for routine inspection and cleaning.
This is particularly relevant when processing aluminum materials where accumulated particles or residue on contact surfaces may affect appearance.
The line combines three core material-handling functions, reducing the need to arrange each function as a completely separate machine.
The integrated configuration supports a coordinated coil-to-press process. Actual layout and space requirements depend on the machine dimensions, coil loading arrangement, and surrounding production equipment.
The hydraulic loop bridge provides temporary material storage between the leveling and feeding sections.
Photoelectric sensing supports loop monitoring and speed coordination, helping the system accommodate differences in material movement between the two sections.
